Solution
The correct option is A the spread of the temperatures is from 70∘F to 79∘F <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->
Since the number of dots corresponding to 75°F is the maximum, 75°F was observed for the maximum time.
The spread of the temperatures is from 70°F to 79°F.
Since there are no dots corresponding to 76°F, none of the days had an average temperature of 76°F.
